KingSlayer, (King Slayer) a didactic open source chess engine by Harm Geert Muller written in C and compliant to the Chess Engine Communication Protocol, published in fall 2015 intended to be an inspiration for beginning chess programmers [1]. KingSlayer is released through a single source file simple.c along with its Makefile and README in a git repository [2]. The extensively commented source code illustrates HGM's favored search techniques and control structure without an outer iterative deepening loop, but IID, some goto statements, and the delayed-loss bonus [3] [4].
